Question

阅读理解 　　It seems to us that the earth stands quite still(静止的)．But it is really moving all the time．It turns around a make-believe line through its center．We call this make-believe line the earth’s axis(地轴)．The two ends of the earth’s axis are called its poles(极)．The earth travels twenty-four hours around its axis once． 　　We look at the sun and say it “travels” across the sky, but the sun doesn’t really do so．The turning of the earth makes us feel as if the sun were moving across the sky．We can’t see that the earth is moving because everything else on the earth is turning with us．As the earth turns around every twenty-four hours, first one half faces the sun and then the other half．When our half of the earth is facing the sun, we say it is “day”．When our half is away from the sun, we say it is “night”．It is the turning of the earth that tells us when to go to bed and when to get up． (1) The meaning of “a make-believe line” is “a line that ________”． [　　] A． is called pole B． we can’t see C． anyone can see D． we can make and believe (2) It takes the earth ________ to turn around its axis once． [　　] A． a week B． a month C． 12 hours D． 24 hours (3) Usually we say, “The sun rises in the east and sets in the west．” In fact, the sun ________． [　　] A． does not move B． is moving all the time C． moves sometimes D． is too heavy to move (4) We can’t see the earth moving because ________． [　　] A． the earth stands still B． everything on the earth is moving with us C． the earth is smaller than the sun D． the earth goes only at night (5) When our part of the earth turns away from the sun we have “________”, and when our part faces the sun we have “________”． [　　] A． day; night B． day; day C． night; day D． night; night

Answer 1

答案：1．B;2．D;3．A;4．B;5．C;
解析：

(1)	根据句子的意思及地理课上学到的知识，可知地球绕其中心旋转的那条线叫做地轴．这是一条假想的、看不见的东西．故答案是B．
(2)	根据“The earth travels twenty-four hours around its axis once．”这个句子可直接选出正确答案．事实上，确切地说，地球自转一周所用的时间是23时48分46秒．
(3)	答案就在“…but the sun doesn’t really do so．The turning of the earth makes us feel as if the sun were moving across the sky．”这两句话中．选项D迷惑性较大，但是这利用由地理知识来排除．
(4)	这是表层理解题，很明显答案在“…because everything else on the earth is turning with us”一句中．
(5)	只要理解了“When our half of the earth is facing the sun, we say it is ‘day’．When our half is away from the sun, we say it is ‘night’．”这句话中face的意思，即它在此处用作动词(意思是“对着；面向”)，答案即可迎刃而解． 　　这是一篇介绍地球的自转、公转以及昼夜的交替等自然现象的成因的短文．借助地理学知识，是不难理解的．
